CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 259,307, dated June 13, 1882.

Application filed April 6, 1882. (No model.)

.To all whom it may concern Be it known that I, LYMAN HATFIELD, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Gar-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to car-couplers and it consists in the peculiar construction of the same, as will be hereinafter fully set forth and claimed.

In the drawings, Figure l is an isometric view, showing two draw-heads with my coupler attached, showing the said draw-heads in position to be coupled. Fig. 2 is a longitudinal vertical section taken through my coupler. Fig. 3 is aplan view of a draw-head, showing my coupler from the top. Fig. 4 is a sectional view, showing another manner of constructin g my coupler for use on flat or lumber cars.

A is a draw-head of suitable construction, which is provided with a socket, a, for the reception of the link. In the rear of the socket a, Iform an oblong slot, 1), which extends vertically through the draw-head A.

B is a coupling-pin, which is secured at its upper end to what I call a carrier, 0. My preferred manner of securing the pin B to the carrier G is shown in Fig. 2, which consists in bending the top portion of the pin n-shaped and forming two key seats or slots, 0 0, on each side, into which fit two spring-keys, cl d, said keys (I (I also engaging with slots formed in the head of the carrier. This construction allows of the pin B being easily removed and replaced when it is worn or broken.

The carrier 0 is provided with a shank, D, which is formed somewhat longer than the coupling-pin B, and is also provided with a shoulder, e, which rests on the end of the coupling-link E and acts to hold it in a horizontal position, and thus guide the said link into the socket to of the opposite draw-head, as shown in Fig. 1, and by lifting the carrier 0, and thus raising the shoulder e from the end of the link E, itallows the opposite end of the said link to fall, as shown in Fig. 2, and thus, where the opposite draw-head is lower, thelink E is guided thereto in this manner. When it is desired to raise the outer end of the link E the carrieris pushed downward, and the shoulder e is thus caused to press on the inner end of the link, and forces said end down into a depression, f, formed in the lower face of the socket a. (See Fig.4.)

F is a crank of peculiar construction, it being formed as shown in Figs. 1 and 3, and acts to first raise the carrier 0 and pin B, and then support the same in a slanting position, as shown in Fig. 1 at the right. This crank slides in an elongated opening, 9, formed in the top of the carrier 0, as shown in Fig. 4, or preferably formed as shown in Figs. 1, 2, and 3--viz., by leaving a space between the upper bent portion of the pin B and the head of the carrier 0.

A rod, rope, or chain, G, may be attached to the carrier and link, if desired, so that the coupler may be operated from the top of the car, if desired.

Instead of placing the crank F above the draw-heads, as shown in Figs. 1, 2, and 3, it

.may be placed beneath the same, as shown in Fig. 4.

The operation of my coupler is as follows: The link E being held in a horizontal position, as shown to the left in Fig. 1, or in any desired position, so as to be guided to the socket a in the draw-head A to the right, and the carrier 0 and pin B being in the position shown to the right, Fig. 1, the outer end of the link E strikes the shank D of the carrier, which acts to bring the carrier 0 and pin B to a vertical position, when it drops of its own weight into proper position, the pin B dropping through the opening in the link E, as shown in Figs. 2 and 4.

When it is desired to uncouple,all that is necessary is to raise the carrier and pin and thus release the link.

What I claim is 1. In a car-coupler, the combination, with the slotted draw-head, of a pin, B, of inverted- U shape, a carrier secured to said pin, and provided with a shoulder, e, and shank D, and a crank secured to theupper end of the pin and adapted to hold the pin and carrier in position for coupling, substantially as set forth.

2. In a car-coupler, the combination, with a draw-head provided with a vertical slot, of a n-shaped pin, and a carrier adapted to extend through said slot, said carrier being keyed to I whereby the pin is secured to the carrier, sub- 10 the upper end of the pin and provided with a stantially as described.
